Question

Each of the three figures below shows three 3 digit numbers, one below the other. Find the odd one out.

(1)	(2)	(3)
583	658	482
146	314	157
729	962	639

• A. Only (1)
• B. Only (2)
• C. Only (3)
• D. None of these

Hint:

Check whether the bottom number in each figure equals the sum of the two numbers above it.

Answer 1

The Correct Option is B

Step 1: Look for a link between the top, middle and bottom numbers.
With three numbers stacked in each figure, a common pattern in this kind of question is that the bottom number equals the sum of the top two. Test this on figure (1) first.

Step 2: Check figure (1).
Top number is 583, middle number is 146.
\[ 583 + 146 = 729 \]
This matches the bottom number of figure (1), which is 729. The pattern holds here.

Step 3: Check figure (3).
Top number is 482, middle number is 157.
\[ 482 + 157 = 639 \]
This matches the bottom number of figure (3), which is 639. The pattern holds here too.

Step 4: Check figure (2).
Top number is 658, middle number is 314.
\[ 658 + 314 = 972 \]
But the bottom number given in figure (2) is 962, not 972. The pattern breaks here.

Final Answer:
Figures (1) and (3) both follow the rule that the bottom number is the sum of the top two, but figure (2) does not, so figure (2) is the odd one out. \[ \boxed{\text{Only (2)}} \]
